Most people have no idea goblins live in the woods around the small town of Bellwater, Washington. But some are about to find out. Skye, a young barista and artist, falls victim to a goblin curse in the forest one winter night, rendering her depressed and silenced, unable to speak of what happened. Her older sister, Livy, is at wit's end trying to understand what's wrong with her. Local mechanic Kit would know, but he doesn't talk of such things: he's the human liaison for the goblin tribe, a job he keeps secret and never wanted, thrust on him by an ancient family contract.

Then Kit starts dating Livy, and Skye draws Kit's cousin Grady into the spell through an enchanted kiss in the woods. Skye and Grady are doomed to become goblins and disappear from humankind forever, unless Livy, the only one untainted by enchantment, can unravel the spell by walking a dangerous magical path of her own.
